# Enlargement geometry definition

An enlargement is a transformation which changes the size of an object without changing its shape, rather as a projector enlarges the details of a photographic slide onto a screen.Note: here we call it resizing, but other people call it dilation, contraction, compression, enlargement or even expansion.Some of the worksheets for this concept are Work on years, Enlargements and reductions work, 4 8 dilations, Unit 7 similarity and transformations grade 9 math hecto, Pa finding scale factor work, Fully describe the single.Examples find use proportions to find missing measures of segments between parallel lines.

Euclidian Geometry is the study of shape, size, position and space.Selection File type icon File name Description Size Revision Time User.The presentation covering such content will be done by the instructor in own handwriting, using video and with the help of.

In the above figure, If two central angles of a circle (or of congruent circles) are congruent, then their intercepted arcs are congruent.A scale factor is used in many applications that involve similar figures, including blueprints and models.
